Neo4j-admin import command for community edition

Per Cloud & Self-Hosted Graph Database Platform Pricing | Neo4j Pricing , Community Edition is only allowed 1 database and to which the default is named neo4j. It should also be noted that one can only run neo4j-admin import into a empty/new database, as well as the database should not be online. Given Community, one would stop all of Neo4j and then run neo4j-admin import and import into the database named neo4j
